Question

X-2/3 + X+1\4 = 6

Ajude-me com a resolução dessa equação ​

Answer 1

x-2/3 + x+1/4 = 6 ===> *(12).mmc

12(x-2)/3 + 12(x+1)/4 = 12*6

4(x-2) + 3(x+1) = 72

4x-8 + 3x+1 = 72

7x -7 = 72

7x = 72 +7

7x = 79

x = 79/7

Answer 2

$\mathsf{x-\dfrac{2}{3}+x+\dfrac{1}{4}=6\times12}\\\mathsf{12x-8+12x+3=72}\\\mathsf{24x=72+8-3}\\\mathsf{24x=77}$

$\mathsf{x=\dfrac{77}{24}}$
